The document lists emissions level targets (IMO I, 2000–2010), displacement, rated rpm, bore and stroke, cooling and lubrication system capacities, and maintenance interval guidance. Standard engine equipment includes sea water aftercooling, auxiliary seawater pumping, fuel and oil filtration components, and key service gauges. Performance tables provide max power and prop demand data for 350 bhp and 420 bhp E ratings across multiple rpm points, plus rating definitions and
